That question got me thinking: In which major disaster would there have been time to get people off board and deploy parachutes? Any major disaster I can think of happened so fast or unbeknownst to anyone on board, or in unfavorable conditions for parachutes, i.e. takeoff or landing.

The only one coming to mind is the Gimli glider and that turned out fine.

All sizes in this video are easily comprehensible. I can grasp a grain of rice. I can grasp a couple and a portion I would eat. A portion my whole family would have for dinner and then a portion a restaurant might use in a busy hour.

With the cube videos it's mostly "This is a cube of 1m³." Which is already hard to encounter IRL and have a good concept of. But then it becomes "now all cubes cover the area of Manhattan higher than the Burj Khalifa". Yeah, those are sizes we know but that are astounding precisely because we cannot really grasp their vastness or tallness.
